Aerodynamic profile

Abstract

Aerodynamic profile that comprises two zones or main sections: one is the front surface inclined with a positive angle, generating the totality or greater part of the lift, and the other is the rear portion or zone to the front surface, profiled or streamlined, formed by two curved, generally hollow surfaces and, which does not generate lift, but leads the air flow properly reducing drag and avoiding boundary layer separation.

1 . An aerodynamic profile, comprising; 
 a first zone on a front surface of said profile, wherein said first zone is inclined at a positive angle to generate lift;    a second zone on a rear surface adjacent to said front surface, wherein said second zone is faired or streamlined, formed by at least two surfaces, and hollow, which does not generate lift; and    wherein said profile reduces drag and substantially reduces separation of the boundary layer.    
     
     
         2 . An aerodynamic profile according to  claim 1 , wherein said second zone has two convex surfaces.  
     
     
         3 . An aerodynamic profile according to  claim 1 , wherein said second zone to said first zone has a flat lower surface that is rigid, and a curved upper surface.  
     
     
         4 . An aerodynamic profile according to  claim 1 , wherein a periphery of said first zone includes a small projecting flange.  
     
     
         5  (Cancelled).  
     
     
         6 . An aerodynamic profile according to  claim 1 , wherein said profile is arranged longitudinally.

         8 . An aerodynamic profile according to  claim 1 , wherein said second zone is rigid.  
     
     
         9 . An aerodynamic profile according to  claim 1 , wherein said second zone is flexible.  
     
     
         10  (Cancelled).  
     
     
         11 . An aerodynamic profile according to  claim 1 , wherein said second zone is at least partially free and rotary.  
     
     
         12 . An aerodynamic profile according to  claim 11 , wherein said second zone is driven by a ram.  
     
     
         13 . An aerodynamic profile according to  claim 1 , wherein said first zone is flat  
     
     
         14 . An aerodynamic profile according to  claim 1 , wherein said first zone is curve.  
     
     
         15 . An aerodynamic profile according to  claim 1 , wherein an upper zone of the nose or leading edge is curved.
